ABSTRACT:
Dripless liquid training/feeding containers, being either a cup and/or a bottle, are described, particularly useful and suitable for babies, toddlers, as well as others requiring them. In operation, a liquid is first placed into, for temporary storage within the container's liquid housing. The container housing is then enclosed by a removably-mounted container sealing lid. During use by a baby or toddler, the liquid stored within the container, is slowly sucked or sipped out of the container's liquid housing, by means of a liquid outlet control valve, incorporated preferably within the container's sealing lid. As the liquid is removed by the user sucking or sipping through the liquid outlet control valve, located within a drinking spout, an air inlet control valve, which may preferably be also incorporated within the container's sealing lid, or in the liquid housing acting in concert with the liquid leaving the container, allows air to flow into the cup, during the sipping, resulting in equalization of the interior/exterior pressures, which, at the same time, results in filling of the space previously occupied by the liquid, that has been sipped out of the cup housing. During the sipping/sucking process, as well as non-use, the container, in all likely orientations and movements, will not drip its liquid contents, while outside the user's mouth.
